Hi, your job is to interpret a function f(x) that is implemented in the ./temp/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp/function.py string). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp/function.py string1 string2 string3 ...). 
We encourage testing a large range of inputs before writing a description.
The goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
Your description of the function should be in the following form.
[DESCRIPTION]: Describe what the function is doing in language. 
[CODE]: Write python code that approximates the behavior of the function.

Let's start by running a few tests on the function with different inputs.

COMMAND: PYTHON(./temp/function.py "apple" "hello" "123")
user:
Response: Function input - output pairs: (apple, apple) (hello, hellN) (123, 123) 

assistant:
Interesting, let's try some more inputs to better understand the function.

COMMAND: PYTHON(./temp/function.py "world" "Computer" "Pattern" "Aa" "Bb" "Cc")
user:
Response: Function input - output pairs: (world, wNrld) (Computer, CNmputer) (Pattern, Pattern) (Aa, Aa) (Bb, Bb) (Cc, Cc) 

assistant:
Let's test a few more inputs for a better understanding.

COMMAND: PYTHON(./temp/function.py "Orange" "Examination" "simple" "Test123" "Mango")
user:
Response: Function input - output pairs: (Orange, Orange) (Examination, ExaminatiNn) (simple, simple) (Test123, Test123) (Mango, MangN) 

assistant:
Based on the provided responses, it seems that the function is replacing the letter "o" with "N" in the input string, and if there's no "o", the output is the same as the input. Here's the description and code:

[DESCRIPTION]: The function replaces the letter "o" with "N" in the input string, leaving all other characters unchanged.

[CODE]:
```python
def approximate_function(input_string):
    return input_string.replace('o', 'N')
```
